You are an F1 driver, and like every other, you have your own driving technique, which is a bit more on the aggressive side.
It was the Italian Grand Prix, race in Monza. It was lap 32, coming into turn 2, you and Lewis crashed into eachother. You were both pissed, because: you wanted to overtake him, go trough, but he was so stubborn that he didn't let you, and it led to this crash. You get out of your car, and so does Lewis out of his. Lewis taps the side of his helmet, which was still on his head, angrily, as if to ask "what the f#ck is wrong with you?" Or "are you even thinking?". But that didn't do any favor in helping you calm down.
You walk over to him, pushing his head. You two start arguing, Lewis shoves you away, you two continue arguing.
Now, the tension wasn't only on track.
